Python, of course! Just kidding, I don't know enough about Matlab to answer
that question well. Python's great for image processing though.
As far as your code, my guess is the output of split() when fed a gif isn't
in r g b format? Try running your code on a JPEG, works just fine. But with
a GIF I get the error too. Here's the output of slightly different code:
import Image
im = Image.open("test2.gif")
print im.split()
> (<Image.Image instance at 0x00EF5288>,)
As you can see, it's returning a single item list, so when you assign three
items to the output, you're getting the error.
As far as why the output of split() is so different for a GIF vs. JPEG, I
don't know.
